There are small typos in:

• SimpleCV/Camera.py
• SimpleCV/Display.py

• SimpleCV/ImageClass.py
• SimpleCV/base.py
• SimpleCV/examples/detection/CannyCam.py
• scripts/install/win/OpenKinect/freenect-examples/demo_cv_thresh_sweep.py

Fixes:

• Should read correspondence rather than correspondonce.
• Should read yields rather than yeilds.
• Should read threshold rather than threshhold.
• Should read through rather than throught.
• Should read submitting rather than submiting.
• Should read specify rather than spicify.
• Should read occurrence rather than occurence.
• Should read coordinates rather than cooridnates.
• Should read array rather than arrray.
